To 4null whom 'it may concern:

.lilo it. known that I JAMES A.. THOMPSON, u itlzen of. the UnitedStates, residing at with un arched opening 4 nt the bottom of Wh ich anincline is arranged. A platform 6 extends from the opening und supportsn l'lonston, in the county of HurrisI und Stute chute 7 coveringtheopening 4 undlnwing u of'Texns, having invented u new und useful(lurlmgo-Crexnutory, of which the following is u spwtoation.

.My invention relatos to new und useful improvements in garbagecrenmtories.

'hc object of thc invention is to provide a crcumtory constructed tocrenlule garbage without the use of fuel other thun the gui'N lingeitself und arranged to first dry the garbage to such an extent us toenable it to iufinerutrl itself.

A 'further object to proridiI nwuns for producing thcV required t'orccil`dl'ut'l und also the production of u reinforced furnace constructed towithstand the intense heut rcsultipo from the .crelnuting of thegarbage.

Finally the object of` the invention is ,to provide u device of thecharacter described that will he strong, durable, simple, eiiioient. umdcomparativelyinexpensive to construct um! also one in `whichthe severalparts will not be liable lo get. ont of ,working orderA i W'ith theabove and other objects in view, my invention hns relation to certainnovel features of operation and construction, un example of which isdescribed in the followingTsg'x-.iioation sind illustrated in theacoompaqiymg drawings, whereln :A

It is obvious that in order to properly incinerate the garbage apowerful draft must be provided. In order to produce a forced draft asuitable blower engine 25 is conneeted with the boiler 14 by a pipe 2G.A.

pipe 2T extends fronl'the engine throughl the base of the furnace to theash pit 23 while a pipe 28 enters the opposite side of the ash pithaving Aconmiunication with the pipe 27 by a branch pipe 2t) extendingaround the base of the furnace as shown .in It`igs. 4 and 5.

It is apparent that garbage deposited in this furnace will be firstdried .so as to freely burn, it being understood that in starting thefurnace a re is first kindled on the main grate 18. The garbage beinfydried and fallin upon the main rate will be uickly bnrne or incinerated,iowever, shou d any part thereof fall through the grate 1S ity will ecaught and consumed upon the undei= lyin grate 19.

i hat I claim, is:

1. In a garbage ereniatory, the combination with a furnace bod having afuel receiving opening, of an inclined water tube grate arranged belowthe opening so as to reoeive fuel therefrom, a horizontal grate arrangedseine distance below the water tube rrate and udaptedto receive the fuelthere reni, and a second horizontal grate arranged below the firsthorizontal grate, said Second grate li-.ivinglsnialler openings than thefirst horizontal grate and arranged to provided in t receive unconsumedfuel passing through the first horizontal grate.

:2. ln a garbage creinalory, the coinbination with a furnace body havinga fuel receiving openin il'. of inclined water tube gratesarrangeiflbeloir the opening, a main grate .supported below theI watertube grilles, a secondary gratesupported below the main grate, draftregulating means associated` with the main grate, and draft regulatingmeans associated with the secondaur grate.

ll. In a garbage creinatory, a furnace co1nprising a frate 18,oppositely arranged pre liminar)I trying grates 10 arranged tosuceessively support the material at points above the grate and todeliver the material to the grate, the grates bein 1 in combination withan incline .3 arrange in approximate alinement with the first grate 10,but at a .somewhat greater inclination for guidingl the matter after itsintroduction into the furnace to said grate, substantially as described.

l. In a garbage creinatory a, furnace com# prising the'prelnninaiyburning grate 18. a second burning grate YS) arranged to receivematerial from the Urate 1S, andla pair of oppositely incliner grates l()adapted to initially support the material and arranged'above the burninggrates and adapted to deliver the material to said grates,-substantially as described.

In a garbage ereinatory, a furnace comprising a burning grate,preliminary drying grate-s arrangeddn staggered relation thereabove,said grates being fixed in position and inclining in oppositediret-.tionsl toward each other from points nearI the side walls of thefurnace to approximately the vertical center thereof whereby tosuccessively support the material and acting by gravity to feed thematerial to the 'burning grate, 'substantially described.
